I used to work with a guy who sometimes wore a t-shirt which said this:

It's a little joke on the seven layer OSI model for computer networking. The joke is that eighth, bottom layer.

Lately the diagram has been on my mind, because I've been thinking it's true of a lot of things, not just networking.

You need only look at a map of the world colored by TV broadcast standard (NTSC, PAL, and SECAM) to see how very true that hidden "zeroth layer" is.
